Job summary

Fospha is hiring a junior software engineer in London to work across the full stack, from Frontend UI in React/Next.js to backend services in Python. You’ll collaborate with engineers, product managers and AI agents in our AI-first operating model, gaining ownership of features from day one.

You will contribute to code reviews, learn spec-driven development, and grow within a supportive team that values high agency and curiosity.

Qualifications

• Some hands-on software engineering experience — internships, placements, personal/open-source projects, or up to ~2 years professional experience
• Working knowledge of React.js or Next.js, a solid foundation in Python, and some exposure to databases (SQL or NoSQL)
• Comfortable being reviewed and iterating on feedback quickly
• Genuine attention to detail and a real interest in why something broke, not just that it did
• Curiosity about AI-assisted development and a willingness to learn spec-driven ways of working
• Confident asking for help and pushing for clarity rather than staying blocked

Responsibilities

• Deliver small-to-medium features independently — frontend UI in React/Next.js, backend services and APIs in Python, working with databases (Aurora PostgreSQL, DynamoDB) — with decreasing need for step-by-step direction
• Write clean, tested code, and grow your ownership within a system area over time
• Participate actively in code reviews and design discussions — giving and receiving candid feedback
• Own bug resolution and act on QA feedback, improving test coverage as you go
• Work with AI agents as part of our AI-first operating model, learning to write clear specifications that shape high-quality, AI-assisted engineering work
• Collaborate proactively with product managers, designers, and fellow engineers to turn requirements into working software
• Get involved across the full Software Development Lifecycle — planning, execution, release, and production monitoring
• Start building the habits of ownership: consistent delivery, low rework, and steady, visible skill growth
